The loft looks exactly as advertised and is located in an alley off the main street which makes a little hard to find but easy to once you figure it out. We called the number provided and someone picked up immediately to wave us in the right direction.
It's near tons of shops and you'll have no trouble finding the plentiful array of street foods and things for sale at the night market.
It's a safe walk from the BTS station if you're coming from the airport, but a cab ride is probably easier and faster. The driver had no problem finding the place once we showed him the address.
